Water fountain return fitting for swimming pools and spas

ABSTRACT

The high flow water return fitting of the present invention is designed to connect directly to the end of a water return pipe in a swimming pool, spa, or the like. Water return fittings have been available for many years and have the primary purpose of returning filtered water back into a swimming pool, spa, or the like. However, the water return fitting of the present invention does not only return water into the swimming pool, spa, or the like, it also redirects the water outflow above the water surface, producing a fountain of pressure regulated airborne stream of aeriated water, substantially increases the area of water in the pool that can be circulated or agitated,

SUMMARY OF THE INVENTION

The present invention is a water return fitting that connects to the endof a water return line in a swimming pool, spa, or the like and throughwhich filtered water is pumped back into the swimming pool, spa, or thelike. A unique curved pressure adjustable tube operates in conjunctionwith a adjustable head and various nozzle to produce a fountain ofaeriated water into the swimming pool, spa, or the like.

Yet another object of the present invention is to provide a detachablefitting to allow ease of mounting and providing disconnection whenminimal force is applied to the return fitting preventing a safetyhazard to swimmers.

Yet another object of the present invention is to provide a water returnfitting that can rotate 360 degrees

Yet another object of the present invention is to provide a water returnfitting with a nozzle that can rotate 360 degrees.

Yet another object of the present invention is to provide a pressureregulation method via the perforated tube and sleeve alignment.

Yet another object of the present invention is to provide a water returnfitting that is length adjustable enabling the nozzle to protrude abovethe water surface regardless of the distance from the water return lineand the water surface.

Yet another object of the present invention is to provide a water returnfitting that is easy to install into the end of a water return line andis manufactured out of plastic material to reduce cost and eliminaterisk of corrosion.

Yet another object of the present invention is to provide a water returnfitting with multiple parts that can be easily assembled correctlywithout the need of special tools or equipment.

The above objects and other features of the present invention, as wellas the structure and operation of various embodiments of the presentinvention, are described in detail below and with reference to theaccompanying drawings.
